generate-cmdlist.sh: avoid selecting synopsis at wrong place

sha1_file.c: resolve confusion EACCES vs EPERM
An earlier commit 916d081 (Nicer error messages in case saving an object
to db goes wrong, 2006-11-09) confused EACCES with EPERM, the latter of
which is an unlikely error from mkstemp().
This avoids the following misleading error message:
error: unable to create temporary sha1 filename ./objects/15: File exists
mkstemp can fail for many reasons, one of which, ENOENT, can occur if
the directory for the temp file doesn't exist. create_tmpfile tried to
handle this case by always trying to mkdir the directory, even if it
already existed. This caused errno to be clobbered, so one cannot tell
why mkstemp really failed, and it truncated the buffer to just the
directory name, resulting in the strange error message shown above.
Note that in both occasions that I've seen this failure, it has not been
due to a missing directory, or bad permissions, but some other, unknown
mkstemp failure mode that did not occur when I ran git again. This code
could perhaps be made more robust by retrying mkstemp, in case it was a
transient failure.

date/time: do not get confused by fractional seconds
The date/time parsing code was confused if the input time HH:MM:SS is
followed by fractional seconds. Since we do not record anything finer
grained than seconds, we could just drop fractional part, but there is a
twist.
We have taught people that not just spaces but dot can be used as word
separators when spelling things like:
$ git log --since 2.days
$ git show @{12:34:56.7.days.ago}
and we shouldn't mistake "7" in the latter example as a fraction and
discard it.
The rules are:
- valid days of month/mday are always single or double digits.
- valid years are either two or four digits
No, we don't support the year 600 _anyway_, since our encoding is based
on the UNIX epoch, and the day we worry about the year 10,000 is far
away and we can raise the limit to five digits when we get closer.
- Other numbers (eg "600 days ago") can have any number of digits, but
they cannot start with a zero. Again, the only exception is for
two-digit numbers, since that is fairly common for dates ("Dec 01" is
not unheard of)
So that means that any milli- or micro-second would be thrown out just
because the number of digits shows that it cannot be an interesting date.
A milli- or micro-second can obviously be a perfectly fine number
according to the rules above, as long as it doesn't start with a '0'. So
if we have
12:34:56.123
then that '123' gets parsed as a number, and we remember it. But because
it's bigger than 31, we'll never use it as such _unless_ there is
something after it to trigger that use.
So you can say "12:34:56.123.days.ago", and because of the "days", that
123 will actually be meaninful now.

checkout: Fix "initial checkout" detection
Earlier commit 5521883 (checkout: do not lose staged removal, 2008-09-07)
tightened the rule to prevent switching branches from losing local
changes, so that staged removal of paths can be protected, while
attempting to keep a loophole to still allow a special case of switching
out of an un-checked-out state.
However, the loophole was made a bit too tight, and did not allow
switching from one branch (in an un-checked-out state) to check out
another branch.
The change to builtin-checkout.c in this commit loosens it to allow this,
by not insisting the original commit and the new commit to be the same.
It also introduces a new function, is_index_unborn (and an associated
macro, is_cache_unborn), to check if the repository is truly in an
un-checked-out state more reliably, by making sure that $GIT_INDEX_FILE
did not exist when populating the in-core index structure. A few places

correct cache_entry allocation
Most cache_entry structs are allocated by using the

up to the nearest multiple of 8 bytes (presumably to avoid
memory fragmentation).
There is one exception: the special "conflict entry" is
allocated with an empty name, and so is explicitly given
just one extra byte to hold the NUL.
However, later code doesn't realize that this particular
struct has been allocated differently, and happily tries
reading and copying it based on the ce_size macro, which
assumes the 8-byte alignment.
This can lead to reading uninitalized data, though since
that data is simply padding, there shouldn't be any problem
as a result. Still, it makes sense to hold the padding
assumption so as not to surprise later maintainers.
